Where’s the report that said they were saying the air was safe at Ground Zero?

They weren’t. They said the air at Ground Zero was dangerous and respirators should be worn. That was disregarded or poorly addressed by NYC and FDNY brass who had jurisdiction.

Since you haven’t provided a single link, here’s another for you for ProPublica ripping the EPA for telling the community the air was safe but: > Officials seemed to be sending two distinct messages: telling office workers and residents the air was safe, while repeatedly warning first responders and crews working right on the debris pile to wear protective gear. Those conflicting assurances and warnings given by federal officials left workers and residents unsure what steps to take to protect themselves.

OSHA and NYOSH failed the FDNY there. Not the EPA.
